Carex brunnea

Carex brunnea, the greater brown sedge, is a species of flowering plant in the sedge family. It is native to China, Japan, Korea, Myanmar, Taiwan, Vietnam, parts of east Africa, as well as eastern Australia and Lord Howe Island. This plant is often seen in disturbed, sunny areas in and near rainforest. This is one of many plants described by Robert Brown and was published in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen (1810). Brown recorded the type "(J.) v.v." Brown's name of Carex gracilis was ruled invalid, as the plant had previously appeared in scientific literature in 1784. Published by the Swedish naturalist Carl Peter Thunberg, in Murray's Systema Vegetabilium, 14th edition. ...read more on Wikipedia.
